And as experience shows, many have been the conspiracies, but few have been successful; because he who conspires cannot act alone, nor can he take a companion except from those whom he believes to be malcontents, and as soon as you have opened your mind to a malcontent you have given him the material with which to content himself, for by denouncing you he can look for every advantage; so that, seeing the gain from this course to be assured, and seeing the other to be doubtful and full of dangers, he must be a very rare friend, or a thoroughly obstinate enemy of the prince, to keep faith with you.

经验证明：自古以来，阴谋为数很多，而曾经成功者甚少，因为搞阴谋的人都不能够单枪匹马地干。而且，除了那些他认为是心怀不满的人们之外，不能够找到别的人合伙同谋。但是，一旦你向一个不满之徒吐露你的意图，你就给他一个使他可以获得满足的方法，因为他显然可以期待从这里取得各种好处，当他看到：站在这一方面利益是确定的，而站在另一方面则是不确定的并且充满着危险，如果他笃守信义，他就是你的罕有的朋友，否则就是君主的非常顽固不化的敌人。

The main work can be summed up as follows: Firstly, we studied the thermal-field properties of VCSELs, and analyzed the influences of current spreading, material parameters and operating conditions on the temperature distributions. Secondly, we began with the electrode voltage and calculated the equipotential s distributions, compared the distributions of voltages and current densities in different depths of VCSELs, and then studied the influences of the oxide-confining region with different position or thickness, and the different sizes of the gain-guided aperture and emitting window on the distributions of the injected current density, carrier concentration and temperature in the active region. Thirdly, we realized the coupling of electricity, optical and thermal-fields, worked out the threshold voltage, calculated the distributions of the injected current density, carrier concentration and temperature under different offset voltages, and analyzed the impacts of temperature profile and carrier density on the refractive index, Fermi levels and optical-field. Finally, we gave the equipotential line distributions with considering N-DBR and double oxidized-confining regions, and analyzed theinfluences of N-DBR and double oxide-confining regions on the distributions of the current density, carrier concentration, temperature and optical-field.

具体工作可以概括如下：首先，研究了VCSEL的热场特性，分析了电流扩展，材料参数和工作条件对于温度分布的影响；其次，从电极电压入手，计算出激光器中的等势线分布，并对不同深度处的电压和电流分布进行比较，研究了高阻区的不同位置和不同厚度、限制层和出射窗口半径的大小对电流密度、载流子浓度和温度分布的影响；再次，实现了电、光、热耦合，求出了阈值电压，计算了不同偏置电压下的电流密度分布、载流子浓度分布和热场分布，分析了温度和载流子浓度变化对折射率、费米能级和光场的影响；最后，给出了考虑N-DBR和双氧化限制层时激光器中的等势线分布，分析了N-DBR和双氧化限制层对VCSEL电流密度、载流子浓度、温度和光场分布的影响。

The results show that dynamical ductil-ity dominated final velocity of fragments. During tube expansion, the shear fracture appears preferentially a-long the adiabatic shear bands under positive stress, so the adiabatic shear band determines the size and shapeof fragments. Though the fragmentation behaviour of medium carbon Si - Mn bainific steel is close to that ofsteel 50SiMnVB, medium carbon Si - Mn bainitic steel is an ideal candidate material for the tubular bombs be-cause it is better in dynamical ductility, which can enable the tubes to gain high speeds before fragmentation.

结果表明：材料动态塑性是决定破片最终速度的主要因素；圆管膨胀时外表面形成以剪切为主的裂纹，并向内扩展，接近内表面的绝热剪切带伴随着圆管的膨胀而扩展，并未出现失稳现象，但在正应力的作用下成为优先的断裂通道、决定破片的尺寸和形态；中碳Si-Mn贝氏体钢与50SiMnVB钢的破碎性能相近，但贝氏体钢动态塑性很更好，破碎前的膨胀量较大、更有利于提高破片初速，是弹箭比较理想的候选材料。

Be aimed at the issue that Olympic Games champion already was registered ahead of schedule, actually here has a lot of to see the thing that seems coincidence, a lot of popular of the match project of broken perhaps gold take part in the match athlete especially the material that the sportswoman is like to sports stars is qualitative, should gain the championship only but can prepare Chinese medicine by roasting it in a pan immediately have one's moment, leave only then their gloden future.
